摘要

亚急性联合变性是一氧化二氮滥用的罕见结果，在T2加权MR成像中，脊髓背柱出现高信号。我们报告了一例滥用一氧化二氮的年轻患者的亚急性联合变性病例，这是一种罕见的原因，在该患者群体中很少出现。维生素B12治疗后症状通常是可逆的，放射科医生应该意识到这些发现，以避免延误治疗。

Nitrous Oxide Abuse‐Induced Subacute Combined Degeneration: Classic Neuroimaging Findings on MRI

Subacute combined degeneration is uncommonly a result of nitrous oxide abuse and presents with high signal in the dorsal columns of the spinal cord on T2-weighted MR imaging. We present a case of subacute combined degeneration in a young patient who abused nitrous oxide, which is an uncommon cause and infrequently seen in this patient population. Symptoms are often reversible with treatment of vitamin B12, and radiologists should be aware of these findings to avoid delay in treatment.
